The Nearby Supernova Factory (SNfactory) is an ambitious project to find and study in detail approximately 300 nearby Type Ia supernova at redshifts 0.03 < z < 0.08. This program will provide an exceptional data set of well-studied supernovae in the nearby smooth Hubble flow which can be used as calibration for the current and future programs designed to use supernovae to measure the cosmological parameters. A key ingredient for this program is a reliable supply of Hubble-flow supernovae systematically discovered in numbers greater than ever before using the same techniques as used in distant supernovae searches. In 2002, 35 SNe were found using our testbed pipeline for automated supernova search and discovery. The pipeline uses data from the asteroid search conducted by the Near Earth Asteroid Tracking group at JPL. We present here further results from our efforts in 2003. Improvements in our subtraction techniques and analysis, combined with an improved main searching camera have allowed us to increase our SN discovery rate and we anticipate discovering 100 SNe in 2003.
